We divide 508207 by 20
We want to divide 508207 by 20.

Step 1:
When dividing 5 by 20, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 20

Moving on to step 2:
If we divide 50 by 20, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 40 from 50 leaves us with 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 20

Going ahead to step 3:
108 divided by 20 is 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we subtract 100 from 108, we get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 20

Going ahead to step 4:
20 goes into 82 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 254.0
Deduct 80 from 82 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 20

On to step 5:
The number 20 fits into 20 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 2541.0
If we subtract 20 from 20, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 20

Let's proceed to step 6:
If we divide 7 by 20, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 25410.0
Subtract 0 from 7 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
When dividing 70 by 20, we get 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 25410.3
If we subtract 60 from 70, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 25410.35
Subtract 100 from 100 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25410.35
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25410.35
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 25410.35 with a remainder of 0.0.
